Re: Shrinking text on spiral path

Here's a hacked up version of another script that was posted a month or so ago. You can play with the starting size and the amount of decrease by changing the numbers.

Clik here to view.

// change size of paragraph text

//$.bp();

ChangeSize();

function ChangeSize()
{
    selectedItems = selection;
    // check to make sure something is selected.
    if (selectedItems.length == 0)
    {
        alert("Nothing is selected");
        return;
    }

    endIndex = selectedItems.length;

    for (index = 0; index < endIndex; index++)
    {
        pageObject = selectedItems[index];
        pageItemType = pageObject.typename;

        if (pageItemType == "TextFrame")
        {
            // get the paragraphs from the selection.
            theTextRange = pageObject.textRange;
            paraTextRange = theTextRange.paragraphs;           
            numParagraphs = paraTextRange.length;

            for (i = 0 ; i < numParagraphs ; i++)
            {
                aParagraph = paraTextRange[i];

                charTextRange = aParagraph.characters;
                charCount = charTextRange.length;

                if (charCount > 1)
                {
                    end = charCount;
                    fontSizeChanger = 14/end;
                    currentFontSize = 18;
                    for (j = 0 ; j < end; j++)
                    {
                        theChar = charTextRange[j];
                        theChar.size = currentFontSize;  
                        currentFontSize = currentFontSize - fontSizeChanger;
                    }
                  
                }
            }
        }
    }
}
